DEVICE FOR ATTACHMENT TO WHEELS.

SPECIFICATION forming part of Letters Patent No. 762,131, dated June 7, 1904.

Application filed August 26, 1903.

T0 0. whom it may concern:

Be it known that I, RALPH E. BROWNE, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful Improvement in Devices for Attachment to Wheels, of which the following is a specification.

This invention relates to attachments for fly-wheels on sewing-machines or on any other similar device, and has for its object the production of a device for mounting and turning buff-wheels, emery-wheels, fans, and the like.

In the accompanying drawings, Figure 1 shows a front elevation of my invention applied to the fly-wheel of a sewing-machine, the same carrying an emery-wheel. Fig. 2 is a front elevation of the attaching-frame with the said emery-wheel removed. Fig. 3 is a side elevation of the emery-wheel, showing means for attaching it to the frame. Fig. 4: is a detached sectional view of the spring members of the frame, the same being taken on the line 4 4 of Fig. 2. Fig. 5 is a detailed view of the attaching end of the arm on the emerywheel. Fig. 6 is a sectional view taken on the line 6 6 of Fig. 5; and Fig. 7 is a sectional view through the center of the emery-wheel, showing the manner in which the arm is attached thereto.

In devices of this character it is very important that they should be capable of being readily attached and detached to their carry ing-frame and to the fly-wheel of the machine and that they shall be so constructed that they will run with perfect balance at the highest speed. It is also important that they be capable of readily receiving various kinds of articles for use, such as emery-wheels, fans, buffwheels, and the like. i i

In the drawings, in which similar reference characters designate corresponding parts throughout the several views, 1 represents the fly-wheel of the machine. WVhile the invention is illustrated as applied to a machine of this character, such machine is shown merely for the purpose of clear illustration, it being understood that the device can be applied to various kinds of machines.

- The carrying or attaching frame ofthe de- Serial 170,762. (No model.)

vice is composed of pieces of'spring metal, (shown at 2 and 3,) said pieces standing at right angles to each other and being secured together at their centers by means of shoulder-rivets 4. Theserivets separate the two pieces a distance suflicient'for the insertion of the end of the arm 5, which carries the emery-wheel 50.

The spring-pieces 2 and 3 are of the substantially semicircular form shown in Fig. 1, and they are bent so that when applied to the wheel they will grip its periphery with sufficient force to cause the frame of the wheel carried thereby to turn and run steadily. For more securely gripping the fly-wheel the said spring-pieces are provided with curved portions, (shown at 6.)

The arm 5 is attached to the emery-wheel or to any other kind of an article that it is desired to use by means of rivets 7 (shown in Fig. 7,) said rivets being preferably split at one end, as at 8, so that they can be readily upset against the wheel. The end of the arm 5 that is attached to the carrying-frame pieces 2 and 3 is bifurcated, as shown in Fig. 5, the two fingers 9 being passed on opposite sides of the rivet 4, which is designated a in Fig. 2, and between the other two of said rivets, so that the arm is forced to turn with the said frame. To prevent the arm from becoming accidentally detached, the lower ends of these fingers are notched, as shown at 10 in Fig. 6, said notches engaging with the lower edge of the spring-plate 3 when the said arm is in engaging position, as shown in Fig. 1.

From the above description it will be understood that when ihe device is to be attached to a wheel, as shown in Fig. 1, it is only necessary to slightly spread the open ends of the springplates 2 and3, when they will slip over the periphery of the wheel into a position where they will be held by their own resiliency. Also when it is desired to attach an emerywheel or any other article it is only necessary to thrust the fingers 9 into the space between the plates 2 and 3, as above described, when the plate 3 will engage in the notch 10 and will avoid accidental displacement of the arm 5.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device for attachment to wheels for the purpose specilicd, an attaching-frame consisting of a plurality of spring-pieces, and means for securing said pieces together substantially in line with the axis of the wheel, said means affording a space between the pieces, and an arm adapted to be inserted into said space, said arm being attached to an emery-wheel or like device.

2. In a device for attachment to wheels, an attaching-frame consisting of spring-pieces that are bent so as to grip the wheel, shouldered rivets for securing said pieces together so as to leave a space therebetwcen, and an arm adapted to be inserted into said space, said arm being attached to an emery-wheel or like device.

3. In a device for attachment to wheels, an attaching-frame consisting of a plurality of spring-pieces, a plurality of rivets for connecting said pieces together, and a forked arm adapted to engage said rivets, certain of said rivets resting between the forks of the arm, and the remaining rivets contacting with the sides of the latter whereby the arm is caused to turn with the spring-pieces and an emerywheel or like device attached to said arm.

4:. In a device for attachment to wheels, an attaching-frame consisting of spring-pieces that are bent to grip the wheel, means for seouring said pieces together so as to leave a space therebetween, and an arm that is adapted to be inserted into said space, said arm being provided with notches so that it can engage with one of said pieces for the purpose specified, and an emery-wheel or like device attached to said arm.

5. In a device for attachment to wheels, an attaching-frame consisting of a pair of springpieces, said pieces being substantially at right angles to each other and being bent to grip the wheel, a plurality of shouldered rivets for securing the said pieces together, said rivets affording a space between the pair of pieces, a forked arm that is adapted to be inserted into said space, so that certain of said rivets will rest between the forks while the others engage the sides of the arm, a notch on said arm into which one of the said pieces engages to hold the arm in position, and an emerywheel or like device attached to said arm.

6. In a device for attachment to wheels, an attaching-frame consisting of a pair of springpieces, said pieces being substantially at right angles and being bent to grip the wheel, three shouldered rivets triangularly arranged, for securing the said pair of pieces together, said rivets affording a space between the said pieces, a bifurcated arm that is adapted to be inserted into said space in such a way that one of said rivets rests between the bifurcations and the others engage with the opposite edges of the arm, notches in said arm with which one of the pieces engages to hold the arm in position, and an emery-wheel or like device attached to said arm.

In testimony whereof I aflix my signature in the presence of two witnesses.
